ABSTRACT In the area of North Tapanuli Regency, a special economic zone for Taman Bunga Tourism will be developed; so that in the future this area will require large amounts of clean water for consumption and water tourism facilities. In order to anticipate this water demand, a research was carried out to determine the feasibility of Lake Toba water in the North Tapanuli Regency area for drinking water raw water and water tourism infrastructure. This research was carried out with in-situ observations and water sampling for analysis in the laboratory according to the procedures of ISO 5667-6:2014 and ISO 5667-3:2012. This study suggests that Lake Toba water in the North Tapanuli Regency area is not yet suitable to be used as raw water for drinking water and water tourism infrastructure because it still has parameters of BOD, COD, Iron, and Barium that do not meet (exceed) the water quality criteria; according to Attachment Number VI to Government Regulation of the Republic of Indonesia Number 22 of 2021 concerning the Implementation of Environmental Protection and Management Keywords: Lake Toba, North Tapanuli, raw water, water recreation, water quality standard.   ABSTRAK Di wilayah Kabupaten Tapanuli utara akan dikembangkan kawasan ekonomi khusus Pariwisata Taman Bunga, sehingga pada saatnya nanti kawasan ini akan memerlukan air bersih dalam jumlah besar untuk konsumsi dan sarana wisata air. Dalam rangka mengantisipasi kebutuhan air tersebut maka dilaksanakan penelitian untuk mengetahui kelayakan air Danau Toba di wilayah Kabupaten Tapanuli Utara untuk air baku air minum dan sarana prasarana wisata air. Penelitian dlaksanakan dengan pengamatan in-situ dan pengambilan sampel untuk analisis laboratorium sesuai prosedur ISO 5667-6:2014 dan ISO 5667-3:2012. Penelitian ini mengisaratkan bahwa air Danau Toba di wilayah Kabupaten Tapanuli Utara tidak layak untuk dijadikan air baku air minum dan sarana prasarana rekreasi air karena masih memiliki parameter BOD, COD, total fosfat, besi, dan barium yang tidak memenuhi nilai baku mutu yang berlaku. Untuk memanfatkan air Danau Toba di wilayah Kabupaten Tapanuli Utara diperlukan upaya penurunan konsentrasi parameter-parameter tersebut. Kata kunci: Danau Toba, Tapanuli Utara, bahan baku air, wisata air, baku mutu.

ABSTRACTThis research was conducted to determine the status of Lake Toba water quality in the area of Toba Samosir (Tobasa) Regency and the feasibility of its use. This study revealed that BOD, COD, iron and free Cl2 of Lake Toba Tobasa regency exceed water quality criteria for Class I and Class II based on Governor Decree No. 1 Year 2009 on Raw water quality of Lake Toba in North Sumatera. High COD and BOD values imply that Lake Toba water was polluted by organic matter presumably originated from floating net cages (KJA), while free Cl2 is thought to originate from domestic waste activities in Parapat City and its surroundings. In general, it was concluded that the water of Lake Toba in the Tobasa Regency did not meet the criteria for clean water and water tourism.Keywords: Lake Toba, raw water, pollution, water qualityABSTRAKPenelitian ini dilakukan untuk mengetahui kualitas air Danau Toba wilayah Kabupaten Toba Samosir (Tobasa) dan kelayakan peruntukannya. Penelitian ini mengungkapkan bahwa air Danau Toba wilayah Kabupaten Tobasa memiliki BOD, COD dan konsentrasi besi dan Cl2 bebas melebihi kriteria mutu air Kelas I dan Kelas II pada Peraturan Gubernur Sumatra Utara No 1 Tahun 2009. Tingginya nilai COD dan BOD mengisyaratkan bahwa perairan Danau Toba tercemar oleh bahan organik yang diduga berasal keramba jaring apung (KJA), sedangkan Cl2 bebas diduga berasal dari limbah domestik kegiatan Kota Parapat dan sekitarnya. Secara umum disimpulkan bahwa air Danau Toba di wilayah Kabupaten Tobasa tidak/belum memenuhi kriteria untuk air baku air minum  dan wisata air.Kata kunci: danau Toba, bahan baku air, pencemaran, baku mutu

Boreal Rivers

The concentrations of trace elements (TEs) in large boreal rivers can fluctuate markedly due to changing water levels and flow rates associated with spring melt and variable contributions from tributaries and groundwaters, themselves having different compositions. These fluctuating and frequently high concentrations create regulatory challenges for protecting aquatic life. For example, water quality criteria do not account for changes in flow regimes that can result in TE levels that may exceed regulatory limits, and neither do they account for the markedly different lability and bioaccessibility of suspended solids. This review addresses the geochemical and biological processes that govern the lability and bioaccessibility of TEs in boreal rivers, with an emphasis on the challenges posed by the colloidal behaviour of many TEs, and their relationship to the dissolved fraction (i.e., <0.45 μm in size). After reviewing the processes and dynamics that give rise to the forms and behaviour of TEs in large boreal rivers, their relevance for aquatic organisms and the associated relationships between size and lability and bioaccessibility are discussed. The importance of biological variables and different forms of TEs for limiting lability and bioaccessibility are also addressed. Two case studies emphasize seasonal fluctuations and accompanying changes in the distribution of TE amongst different size fractions and associated colloidal species in large boreal rivers: the Northern Dvina and one of its tributaries, the Pinega River, both in Russia, and the Athabasca River in Alberta, Canada. Water quality in the Athabasca River is briefly discussed with respect to Canadian guidelines.
